This was the Jhoulys Chacin the Rockies have been waiting for all season.

This was the pitcher who earned the nickname "The Machine" last season when he was in synch and humming to 14 wins and a 3.47 ERA. This was the pitcher who got groundball outs when he needed them most.

Welcome back.

The right-hander blanked the Atlanta Braves for seven innings Thursday afternoon at Coors Field and notched his first win of the season as the Rockies cruised to a 10-3 victory. Paired with an 8-2 win over Atlanta on Wednesday night, it took some of the sting out of a disappointing 3-7 homestand.

"I wasn't feeling very good because the team was losing in all of my starts," said Chacin, now 1-4 with a 4.53 ERA after eight starts. "So I'm happy that I did my job and we won. We had a rough stretch, and hopefully from now on we start winning again."

Things got very heated late in the game, and not just because Rockies hitters continued to pounded Braves pitchers. In the eighth inning, Rockies manager Walt Weiss and Atlanta reliever David Carpenter were both ejected. Weiss was angrier than Rockies fans have ever seen him.

Weiss' players will tell you that their manager has a burning intensity and a temper, he just doesn't display it very often to the baseball public.

"I don't like to show it," Weiss said. "I don't like to go there. The stuff I do is behind close doors. I'm not here to entertain anybody. I don't like to go there, but it happened."

The near-fracas begin when Corey Dickerson's backswing on a foul tip caught catcher Gerald Laird's facemask and jaw, knocking Laird to the ground and out of the game. Then, on the next pitch, Carpenter drilled Dickerson in the back of the thigh, and Carpenter was immediately tossed.

Dickerson appeared ready to go after Carpenter, but Weiss intervened. Very quickly, a seething Weiss was shouting at Carpenter, the Braves' dugout and at home-plate umpire Jordan Baker. That's when Weiss got the heave-ho, the second time in the last 13 games he's been ejected. He was never ejected all last season, his first as a big-league manager.

Asked why Carpenter would throw at Dickerson, Weiss answered: "I have no idea. If you think a guy can foul a ball off and then at the same time hit a catcher on the backswing, on purpose, then you've got no clue. They made their decision and they made a bad choice."

The Rockies threw the final shot when reliever Nick Masset drilled newly-inserted catcher Evan Gattis in the ninth. Gattis calmly jogged to first while Masset was immediately tossed, along with Rockies bench coach Tom Runnells.

Braves manager Fredi Gonzalez defended Carpenter.

"I don't think it was on purpose what Carpenter did, (but) the only one who knows that is 'Carp,' " Gonzalez said. "But I don't think it was on purpose. But I understand why (Weiss) is upset, and you know what? It's baseball. (Masset) got us in the ninth inning and (we) went down to first base. We knew that something like that could happen and it happened. I'm really proud of the way Gattis handled that situation."

Carpenter pleaded innocent, saying he didn't understand why the Rockies were upset, adding that the pitch that plunked Dickerson got away from him.

"Dickerson was kind of looking at me and, you know .... you just got hit, go to first base, that's all there is to it," Carpenter said. "Just go on to the next batter.

"I really was (surprised). I was surprised getting tossed out of the game there. I was just preparing for the next hitter and the next thing you know I'm getting asked to leave the field. But I mean I guess it's just how the game goes. You can't let a hitter take away part of the plate. You know we've got to establish (inside) and we didn't do a very good job. I tried to do it and the ball just cut on me."

Chacin, meanwhile, was a model of efficiency, needing only 85 pitches (56 strikes) to get his job done. He walked only two and struck out five.

"It was a very well-pitched game," Weiss said. "We've been through a rough stretch here, but the guys kept fighting and we finished up on a good note."

The only time Chacin even sniffed trouble was when he walked Chris Johnson and Tommy La Stella back-to-back in the seventh. After a short visit on the mound from pitching coach Jim Wright, Chacin threw a sinker to Andrelton Simmons, who grounded into an inning-ending double play.

Rockies' bats ran cold at the beginning of the homestand, but they heated up at the end, and they sizzled Thursday.

Charlie Blackmon put the Rockies on the board in the third with a towering two-run homer off Atlanta starter Ervin Santana. Blackmon's shot, his 12th of the season, stayed just inside the foul pole in the right-field corner. He has 42 RBIs this season, and 40 of them have come from the leadoff spot, most in all of baseball.

Justin Morneau padded the lead with a solo home run to center off Santana in the sixth. It was Morneau's 11th homer.

The Rockies scored five more in the seventh inning, the big hit a two-run single up the middle by Morneau to score Charlie Culberson and Blackmon. They needed the runs, too, because their suspect bullpen let the Rockies down again in the Braves' three-run eighth. Adam Ottavino served up a run-scoring single to Jason Heyward and a two-run homer to B.J. Upton.

The Rockies begin a six-game West Coast road trip on Friday night at San Francisco against the Giants.

Lincecum would fit in perfectly with the Rockies' rotation. In other words, he has been a model of inconsistency this year. The two-time Cy Young Award winner limited the New York Mets to three runs and six hits Sunday and notched his fifth victory. He struck out six and walked only one. The performance came after an awful start in which he gave up eight earned runs, six hits and three walks in 4 innings at Cincinnati. Lincecum will have to be careful with Rockies catcher Wilin Rosario, who is 6-for-16 (two doubles, two home runs) against him.
